Film in a Pinhole Camera
Hmmm... I have been impressed with Acros 100, it seems to me to be a fabulous film in sheets and 120.
I also use a variety for no particular reason than I have it and the cost is low or it was free, e.g., Orwo, Ilford, Kodak.
Pan F can give incredible results as well.
I do not care for C-41 films, so use Velvia/Provia in 120 and 4x5.
If you have a look at one of my recent blog postings, you will note what I have found to be awesome developers for films.
I'm beginning to get the impression that even with pinhole photography, there may be certain combinations of chemistry and films that really work well together.
